Section 2.5 Proving Statements about Segments and Angles 101 Using Properties of Congruence The reasons used in a proof can include de! nitions, properties, postulates, and theorems. A theorem is a statement that can be proven. Once you have proven a theorem, you can use the theorem as a reason in other proofs. Naming Properties of Congruence.

Check the corresponding angles and corresponding sides. Both triangles have sides 5cm 5cm and 7cm 7cm . They both have an angle of 95° 95°. 2 Decide if the shapes are congruent or not. The 95° 95° angles are in a corresponding position. The triangles are mirror images of each other. The triangles are congruent.Choose 1 answer: When a transversal crosses parallel lines, alternate interior angles are congruent. A When a transversal crosses parallel lines, alternate interior angles are congruent. When a transversal crosses parallel lines, same-side interior angles are congruent. BMake sure you know how to identify the different types of angles formed when two lines are cut by a transversal: The angle pairs {2, 8} and {3, 7} are alternate interior angles—you can remember this because they form a sort of “Z” shape or reversed “Z” shape. The angle pairs {1, 2}, {4, 7}, {5, 8}, and {3, 6} are

The first one focuses on angles, the second on lines and angles. The third one puts it all together. Homework 1 - We can see that ∠ABD and ∠CBD form a linear pair, so they are supplementary to each other. Homework 2 - Vertical angles are equal is the lead here. Homework 3 - Knowing that two lines are parallel, you can learn a lot.

Choose 1 answer: When a transversal crosses parallel lines, alternate interior angles are congruent. A When a transversal crosses parallel lines, alternate interior angles are congruent. When a transversal crosses parallel lines, same-side interior angles are congruent. B If a triangle is a right triangle, then it has a 90° angle. 6. If two angles are vertical angles, then they are congruent. 7. If two angles are same-side interior angles, then they are supplementary. New Vocabulary •flow proof x2 What You’ll Learn • To use a transversal in proving lines parallel. . .And Why To show how to paint parallelare congruent to two angles and the included side of another triangle, then the triangles are congruent.
